锁骨钩钢板治疗不稳定性胸锁关节脱位

目的 探讨锁骨钩钢板切开复位治疗不稳定性胸锁关节脱位的临床意义及疗效. 方法 2005年4月至2007年10月,采用切开复位锁骨钩钢板内固定治疗19例不稳定性胸锁关节脱位患者,根据Grade分型:Ⅱ型2例,Ⅲ型17例.全部采用患侧切开复位锁骨钩钢板内固定术加关节成形术并修补肋锁韧带、胸锁韧带. 结果术后均尤再脱位,钢板尤断裂、松动、脱钩等现象.所有患者均获随访,时间6～24个月,平均8个月;愈合时间3～6周,平均4周.按照Rockwood胸锁关节评分标准:优16例,良2例,可1例,优良率为94.7%.术后患者均恢复解剖结构及外观,功能满意.结论 锁骨钩钢板内固定治疗小稳定性胸锁关节脱位具有操作简便安全、创伤小、固定可靠等优点,并有较好的维持复位和促进恢复作用,术后患者功能及外观恢复满意.

Treatment of unstable dislocation of sternoclavicular joint with clavicle hook plates

Objective To discuss the clinical treatment of unstable dislocation of the sternoclavicular joint with clavicle hook plates. Methods From April 2005 to October 2007, 19 cases of unstable dislo-cation of stemoclavicular joint were treated with open reduction and internal fixation by clavicle hook plates. There were 17 cases of Grade type Ⅲ and 2 cases of Grade type Ⅱ. After open reduction and internal fixation, all patients received arthroplasty and repair of eostoclavicular and sternoclavicular ligaments. Results None had intraoperative injury to nerves and blood vessels. Follow-ups from 6 to 24 (mean, 8) months showed 16 excellent cases, 2 good cases and 1 fair case by Roekwood criteria, the good to excellent rate being 94.7%. The healing duration lasted 3 to 6 (averaging 4) weeks. No infection, sliding or loosening of internal fixation, nonunion or re-dislocation was found postoperatively. Conclusion The clavicle hook plate is an effective and advanced surgical treatment of sternoclavieular joint injuries, because its easy and mini-invasive operation can provide sturdy fixation and lead to good functional recovery.
